Bulk HTTP Header Response Checker & Comparison Tool

This tool returns the HTTP response code for a whole list of URLs, and includes which URL they are redirected to where pertinent.

You can optionally fetch each URL twice, with varying user agents and compare them. This can help turn up cloaking issues, such as those page redirecting for GoogleBot. Note: it only checks the response header and redirect location, not the page content.

Update April 2014:

HTTPS URLs now work better.

Now if you enter just a single URL you'll see the full set of HTTP response for each user agent.

I updated and extended the list of user agents.

Added a limit of a 100 URLs to prevent time out issues.

Enforce a 20 second timeout per URL before moving on.

Extended the total timeout limit. It should now always complete, hopefully.

Just enter the list of URLs below and press the button:

Select User Agent:

Select Second User Agent (optional):
